  • Patent number: 7686926
    Abstract: A multi-step process performed in a plasma sputter chamber including sputter deposition from the target and argon sputter etching of the substrate. The chamber includes a quadruple electromagnetic coil array coaxially arranged in a rectangular array about a chamber axis outside the sidewalls of a plasma sputter reactor in back of an RF coil within the chamber. The coil currents can be separately controlled to produce different magnetic field distributions, for example, between a sputter deposition mode in which the sputter target is powered to sputter target material onto a wafer and a sputter etch mode in which the RF coil supports the argon sputtering plasma. A TaN/Ta barrier is first sputter deposited with high target power and wafer bias. Argon etching is performed with even higher wafer bias. A flash step is applied with reduced target power and wafer bias.

  • Patent number: 7674707
    Abstract: Devices and methods are presented to fabricate diffusion barrier layers on a substrate. Presently, barrier layers comprising a nitride layer and a pure metal layer are formed using a physical vapor deposition (PVD) process that requires multiple ignition steps, and results in nitride-layer thicknesses of no less than 2 nm. This invention discloses devices and process to produce nitride-layers of less than <1 nm, while allowing for formation of a pure metal layer on the nitride-layer without re-igniting the plasma. To achieve this, the flow of nitrogen gas is cut off either before the plasma is ignited, or before the formation of a continuous-flow plasma. This ensures that a limited number of nitrogen atoms is deposited in conjunction with metal atoms on the substrate, thereby allowing for controlled thickness of the nitride layer.

  • Publication number: 20100035152
    Abstract: Electrochemical cells or batteries featuring functional gradations, and having desirable, periodic configurations, and methods for making the same. One or more methods, in alone or in combination, are utilized to fabricate components of such electrochemical cells or batteries, which are designed to achieve certain thermal, mechanical, kinetic and spatial characteristics, and their effects, singly and in all possible combinations, on battery performance. The thermal characteristics relate to temperature distribution during charge and discharge processes. The kinetic characteristics relate to rate performance of the cells or batteries such as the ionic diffusion process and electron conduction. The mechanical characteristics relate to lifetime and efficiency of the cells or batteries such as the strength and moduli of the component materials. Finally, the spatial characteristics relate to the energy and power densities, stress and temperature mitigation mechanisms, and diffusion and conduction enhancements.

  • Publication number: 20100021659
    Abstract: A sensor utilizing a non-leachable or diffusible redox mediator is described. The sensor includes a sample chamber to hold a sample in electrolytic contact with a working electrode, and in at least some instances, the sensor also contains a non-leachable or a diffusible second electron transfer agent. The sensor and/or the methods used produce a sensor signal in response to the analyte that can be distinguished from a background signal caused by the mediator. The invention can be used to determine the concentration of a biomolecule, such as glucose or lactate, in a biological fluid, such as blood or serum, using techniques such as coulometry, amperometry, and potentiometry. An enzyme capable of catalyzing the electrooxidation or electroreduction of the biomolecule is typically provided as a second electron transfer agent.

  • Publication number: 20100003511
    Abstract: A transparent electrode multilayer film has at least one group III doped ZnO layer and at least one metal layer, where layers of doped ZnO alternate with metal layers. When a plurality of group III doped ZnO layers are present, the doped ZnO layers can have the same or different dopants and one or more dopants can be present in a doped ZnO layer. When a plurality of metal layers is present, the layers can be of the same or different metals, and a metal layer can be a single metal or a combination of two or more metals. The multilayer film can be free standing, but generally includes a substrate. Advantageous substrates are transparent and can be flexible for use as a flexible electrode. A method to form a transparent conductive multilayer film involves depositing at least one layer of a group III doped ZnO and at least one metal layer on a substrate.
